'CARDING-MACHINE.

Specification of Letters Patent. Patented July 25, 1916,

Applicatioii filed December 27, 1909. Serial No. 535,093.

To all whom it may concern Be it known that we, FRITZ Vos'rER and MAX JUNGBAUER, subjects of the German Emperor, and residents of Augsburg, Germany, have invented Improvements in and Relating to carding-Machines, of which the following is a specification.

This invention relates to apparatus for cleaning the card clothing of carding engines by suction and it relates more particularly to an improved device for traversing the suction opening to and fro over the surface of the card clothing.

In order that this invention may be clearly understood reference is made to the accompanying drawing, in which:

Figure 1 shows the device in side elevation, as applied to a carding machine Fig. 2 shows a detail; Fig. 3 shows a cross section through Fig. 2.

.7) and 0 are two hollow pipes which are arranged parallel with and close to the carding surface a. The outer pipe 0 is revoluble and has a spiral slot (1 (Fig. 2), and the inner pipe I) is fixed and has a longitudinal slot or opening 6. The carding cylinder and the dofler are each provided with a set of pipes 12 and 0. Each pipe I) is arranged with its slot 6 facing either the carding cylinder or the doifer so that as the pipes c revolve an opening will, in each case, be formed where the slots 6 and d coincide and the continued revolution of the pipes will cause this opening gradually to move along longitudinally of the pipes. One end of each pipe I) is sealed and the other is connected to pipes f which are, in turn, connected up to a collecting box C and a vacuum pump P. The collecting box and vacuum pump may be of any known type and are conventionally shown in the accompanying drawings.

For the purpose of rotating the outer tube, it may be provided with a pulley 1 and belt 2 so that it can be connected to a shaft or source of power 3 whereby it can be rotated.

What we claim as new and desire to secure by Letters Patent is 1. In a carding machine the combination with a carding surface of a fixed tube and a rotatable tube arranged parallel to the carding surface and one within the other, the said tubes being provided with slots angularly arranged with respect to each other o that as the rotatable tube turns relatively small portions of the slots coincide to form an opening that gradually moves longitudinally of the tubes, a vacuum pump, a collecting box between the suction tubes and the pump, and pipes connecting the suction pipes and the collecting box and the collecting box and the pump.

2. In a carding machine the combination with a carding surface of a fixed tube and a rotatable tube arranged parallel to the carding surface and one within the other the fixed tube being provided with a longitudinal slot and the rotatable tube with a spiral slot so that as the rotatable tube turns the slots will coincide to form an opening that gradually moves longitudinally of the tugbes across the carding surface; a vacuum pump, a collecting box, and pipes connecting the suction tubes and the collecting box and the collecting box and the pump.

3. In a carding machine the combination with a carding surface of a fixed inner tube arranged parallel to the carding surface and having a longitudinal slot therein, a rotatable outer tube mounted on the inner tube and having a spiral slot so that as it turns upon the inner tube its spiral slot will coincide withthe longitudinal slot in the said inner tube to form an opening that gradually moves longitudinally of the tubes across the carding surface, a vacuum pump, a collecting box, and pipes connecting the suction tubes to the collecting box and the collecting box to the pump.

4c. In a carding engine, the combination with a carding surface, of a vacuum pump, a collecting box, a pipe connecting the pump and the collecting box, a cleaning member connected with said suction box and provided with an elongated suction opening parallel with the carding surface, and means for connecting a relatively small portion of said opening with the atmosphere, and including means for automatically varying the location of the connected portion of said opening throughout the length of the latter.

5. In a carding engine, the combination with a carding surface, of a Vacuum pump, a collecting box, a pipe connecting the pump and the collecting box, a cleaning member comprising a pipe provided with a longitudinal slot parallel with the carding surface,

and a rotatable member mounted on said i In testimony whereof We have hereunto pipe and provided with means for connectset our hands in the presence of two sub- 10 ing a relatively small portion of said slot scribing Witnesses.

with the atmosphere and constructed to au- FRITZ VOSTER. tomatically vary the position of the con MAX JUN GBAUER. nected portion With respect to the ends of Witnesses: said slot and means for connecting said LOUIS I. MUELLET, pipe With said suction box. MATI-IILDE K. HELD.
